'How to Listen to Music' is a non-fiction book intended to help the readers to enjoy classical music better. As the author puts it, the book is meant to serve a simple and straightforward purpose. It is not meant to teach professionals or scholars in the field of music, but rather it is meant for those who enjoy listening to music in concert halls and opera houses but have not studied it in depth. It is not for those who are not willing to consider the deeper meaning and appreciation that comes from considering beautiful music, but for those who are willing to explore the possibilities.
